Is (x,y) a solution to the System of Inequalities?

100

What inequality symbol would you use for the words "at least?"

100

DASHED!

100

What are the two things you need in order to graph a linear equation?

Slope and the y-intercept

100

Graph the system of inequalities

y > x + 1

y > -x

100

Is the point a solution to the system?

No! The point lies on the DASHED line, so you cannot include it in the solution!

200

What inequality symbol would you use for the words "at most?"

200

ABOVE!

200

The line y = -2x - 3 has what y-intercept?

What is -3?

200

200

Is the point a solution to the system?

Yes! This point lies in the shaded region.

(Hint: The tick marks on the graph go up by 5's!)

300

What inequality symbol would you use for the words "no more than?"

300

300

A linear equation defined by m = 2/3 and b = 6 is what equation written in slope intercept form?

What is y = 2/3 x + 6?

300

300

Is the point a solution to the system?

Yes! This point lies on the SOLID line, so it IS a part of the solution!

(Hint: Each tick mark on the graph goes up by 2s!)

400

What inequality symbol would you use for the words "not to exceed?"

400

400

Graph the equation y = -3x + 2.

See teacher for answer.

Is (0,0) a solution to the system of inequalities below?

No! The point (0,0) lies outside of the shaded region.

500

What inequality symbol would you use for the words "no fewer than?"

500

500

What is the slope of the line y = 2/3 x + 1

2/3

Answer: D

(Hint: Plug in "x" and "y" for each point to

see which ordered pair makes the inequalities true statements!)
